If ChromaVerb doesn't show real-time visualization in Logic Pro X

ChromaVerb, an algorithmic reverb plug-in included with Logic Pro X, uses Metal to show a real-time visualization of changes to parameter values and the incoming signal in its main display. The following Macs support Metal:

MacBook (Early 2015 or newer)

MacBook Pro (Mid 2012 or newer)

MacBook Air (Mid 2012 or newer)

Mac mini (Late 2012 or newer)

iMac (Late 2012 or newer)

Mac Pro (Late 2013)

Older Mac Pros with AMD Radeon HD 7xxx graphics card

If your Mac supports Metal, click the Visualization icon in the Chromaverb plug-in window to turn real-time visualization on and off. If your Mac doesn't support Metal, you can still use ChromaVerb without real-time visualization.
